An under layer 101, a first free magnetic layer 102, a non-magnetic layer
104, a fixed magnetic layer 106 and an anti-ferromagnetic layer 107 are
formed in the mentioned order on a substrate 100. The under layer 11 is a
laminate layer 101 is a laminate layer constituted by two or more metal
layers of different materials. The metal layers are formed by using a
member or an alloy of two or more members of the metal group consisting of
Ta, Hr, Zr, W, Cr, Ti, Mo, Pt, Ni, Ir, Cu, Ag, Co, Zn, Ru, Rh, Re, Au, Os,
Pd, Nb and V.
